Hello Gabriel,
first of all thank you very much for testing the bw meter :-) answers follow inline.
You're welcome, I think it's an interesting idea.

Hi Antonio, As you suggested, I've tested the bandwidth meter with batman-adv-devel 38a1b72. I've installed it on two TP-Link WDR-3500 routers.oky. However, since the bw_meter has not been merged yet, its branch changes from time to time because it gets rebased on top of the very latest development code. Therefore, when you decide to update your testbed, I'd suggest you to look at: http://git.open-mesh.org/batman-adv.git/shortlog/refs/heads/ordex/bw_meter and pick the commit ID of the last patch at the top.
If you have problems in doing this, please ask.
I don't understand what commit ids should I use. For example, how could I find the ones you suggested me before for batman (38a1b72b6) and for batctl (eebba0bfb). Because on the top of the git I see for example the commit d672369c3476f002662fa7e83b76ee56a93a76db for "batman-adv: set maximum number of BW session", which seems in a different format, right?
Running normal iperf inside the routers, and without unloading any kernel module, I get 60 Mbps using UDP, 80 Mbps using TCP (I don't understand why TCP works better), and about 4 Mbps with batctl bw -t 10000. Any ideas? By the way, the batctl ping between routers doesn't work, I get time-out. Besides, there's another strange behaviour, when I try to pass traffic from a PC client connected to one router, to the other router using iperf, if I use UDP values of about 100 Mbps, the router that receives the traffic and redirects it, reboots. Thanks.Ok..well, first of all I'd rather check what is wrong in the mesh. If batctl ping does not work, then it means that there is something else which is not working/configured properly.
Yes, it's weird, specially because there's connectivity between routers thanks to batman-adv.
For this reason I'll first suggest you to update to this commit id: d672369 . Then, does "batctl o" properly shows the other node with a "reasonable TQ"?
So, in menuconfig I should select that id for batman-adv-devel right? I wanted to see that commit on the git page using the search field but I couldn't. By the way, how to know which batctl version use with each batman-adv-devel commit? Sorry if all these questions are too basic, but I've tried to compile with this d672369 version and I got some errors, so I'd like to understand if it was related to these things.
By the way, your iperf tests have been done on top of batman-adv? or directly on the wifi interface?
Cheers,
I got the results mentioned using interfaces managed by batman-adv.
Regards
Gabriel
